Automatically enable 'interaction_mode'

[Mimry]

Is there a way to automatically enable the 'interaction_mode' for every .lisp buffer? I couldn't find a setting and I am having troubles finding a workaround. I tried to to set the variable in my init.lua / ftplugins/lisp.lua

vim.fn.setbufvar(vim.fn.bufnr('%'), 'nvlime_interaction_mode', true)

but that didn't work. Any ideas?
